"Ketosis Ketosis is a metabolic state in which some of the body's energy supply comes from ketone bodies in the blood, in contrast to a state of glycolysis in which blood glucose provides energy. Generally, ketosis occurs when the body is metabolizing fat at a high rate and converting fatty acids into ketones. Ketosis is a nutritional process characterised by serum concentrations of ketone bodies over 0.5 mM, with low and stable levels of insulin and blood glucose. It is almost always generalized with hyperketonemia, that is, an elevated level of ketone bodies in the blood throughout the body. Ketone"

"health. Ketoacidosis is an acute life-threatening state requiring prompt medical intervention; its most common form is diabetic ketoacidosis where both glucose and ketone levels are significantly elevated. Ketone bodies are acidic, but acid-base homeostasis in the blood is normally maintained through bicarbonate buffering, respiratory compensation to vary the amount of CO in the bloodstream, hydrogen ion absorption by tissue proteins and bone, and renal compensation through increased excretion of dihydrogen phosphate and ammonium ions. Prolonged excess of ketone bodies can overwhelm normal compensatory mechanisms, defined as acidosis if blood pH falls below 7.35. There are two major causes of ketoacidosis:"
"Ketoacidosis Ketoacidosis is a metabolic state associated with high concentrations of ketone bodies, formed by the breakdown of fatty acids and the deamination of amino acids. The two common ketones produced in humans are acetoacetic acid and β-hydroxybutyrate. Three common causes of ketoacidosis are alcohol, starvation, and diabetes, resulting in alcoholic ketoacidosis, starvation ketoacidosis, and diabetic ketoacidosis respectively. In diabetic ketoacidosis, a high concentration of ketone bodies is usually accompanied by insulin deficiency, hyperglycemia, and dehydration. Particularly in type 1 diabetics, the lack of insulin in the bloodstream prevents glucose absorption, thereby inhibiting the production of oxaloacetate through reduced levels"
"ketosis, which causes a build up of ketones in the blood stream. Ketone bodies are transported across the blood-brain barrier by other means than the Glut1 protein and thus may serve as an alternative fuel for the brain when glucose is not available. Anti-seizure medications are generally not effective, since they do not provide nourishment to the starved brain. While ketogenic diets have been proven effective to control seizures and relieve some movement disorders in many Glut1 Deficiency patients, some patients do not respond as well as others. In addition, some critical symptoms, including cognitive deficits and certain movement difficulties,"

Disease sufferers experience nausea, vomiting, inability to feed, and breathing difficulties. In extreme cases, ketoacidosis can lead to coma and death. The deficiency is caused by mutation in the gene OXCT1. Treatments mostly rely on controlling the diet of the patient.

This deficiency specifically presents as ketosis, acidosis, as well as hypoglycemia, but there are other clinical manifestations as well.

"is a pathological metabolic state marked by extreme and uncontrolled ketosis. In ketoacidosis, the body fails to adequately regulate ketone production causing such a severe accumulation of keto acids that the pH of the blood is substantially decreased. In extreme cases ketoacidosis can be fatal. Ketoacidosis is most common in untreated type 1 diabetes mellitus, when the liver breaks down fat and proteins in response to a perceived need for respiratory substrate. Prolonged alcoholism may lead to alcoholic ketoacidosis. Ketoacidosis can be smelled on a person's breath. This is due to acetone, a direct by-product of the spontaneous decomposition of"

"acidosis are: ketoacidosis, lactic acidosis, renal failure, and toxic ingestions. Ketoacidosis can occur as a complication of type I diabetes mellitus (diabetic ketoacidosis), but can occur due to other disorders, such as chronic alcoholism and undernutrition. In these conditions, excessive free fatty acid metabolism results in the production of ketoacids, acetoacetic acid, and beta-hydroxybuterate. Lactic acidosis results from excess formation and decreased metabolism of lactate, which occurs during states of anaerobic metabolism. It is the most common cause of metabolic acidosis in hospitalized patients. The most serious form occurs during various states of shock, due to episodes of decreased liver"
"Some clinicians refer to this period of keto-adaptation as the ""Schwatka imperative"" after Frederick Schwatka, the explorer who first identified the transition period from glucose-adaptation to keto-adaptation. In dairy cattle, ketosis is a common ailment that usually occurs during the first weeks after giving birth to a calf. Ketosis is in these cases sometimes referred to as ""acetonemia"". A study from 2011 revealed that whether ketosis is developed or not depends on the lipids a cow uses to create butterfat. Animals prone to ketosis mobilize fatty acids from adipose tissue, while robust animals create fatty acids from blood phosphatidylcholine (lecithin)."
"Beta-ketothiolase deficiency Beta-ketothiolase deficiency is a rare, autosomal recessive metabolic disorder in which the body cannot properly process the amino acid isoleucine or the products of lipid breakdown. The typical age of onset for this disorder is between 6 months and 24 months. The signs and symptoms of beta-ketothiolase deficiency include vomiting, dehydration, trouble breathing, extreme tiredness, and occasionally convulsions. These episodes are called ketoacidotic attacks and can sometimes lead to coma. Attacks occur when compounds called organic acids (which are formed as products of amino acid and fat breakdown) build up to toxic levels in the blood. These attacks"

Hyperglycemia results in glucose overloading the kidneys and spilling into the urine (transport maximum for glucose is exceeded). Dehydration results following the osmotic movement of water into urine (Osmotic diuresis), exacerbating the acidosis. In alcoholic ketoacidosis, alcohol causes dehydration and blocks the first step of gluconeogenesis by depleting oxaloacetate. The body is unable to synthesize enough glucose to meet its needs, thus creating an energy crisis resulting in fatty acid metabolism, and ketone body formation. Ketoacidosis"

Signs and symptoms of diabetic ketoacidosis may include: Hyperglycemia caused a decrease in cognitive performance, specifically in processing speed, executive function, and performance. Decreased cognitive performance may cause forgetfulness and concentration loss. In untreated hyperglycemia, a condition called ketoacidosis may develop because decreased insulin levels increase the activity of hormone sensitive lipase. The degradation of triacylglycerides by hormone-sensitive lipase produces free fatty acids that are eventually converted to acetyl-coA by beta-oxidation. Ketoacidosis is"

Ketogenesis can be ineffective in people with beta oxidation defects. Individuals with diabetes mellitus can experience overproduction of ketone bodies due to a lack of insulin. Without insulin to help extract glucose from the blood, tissues the levels of malonyl-CoA are reduced, and it becomes easier for fatty acids to be transported into mitochondria, causing the accumulation of excess acetyl-CoA. The accumulation of acetyl-CoA in turn produces excess ketone bodies through ketogenesis. The result"

Dr. Russell Morse Wilder, at the Mayo Clinic, built on this research and coined the term ""ketogenic diet"" to describe a diet that produced a high level of ketone bodies in the blood (ketonemia) through an excess of fat and lack of carbohydrate. Wilder hoped to obtain the benefits of fasting in a dietary therapy that could be maintained indefinitely.

"Ketogenic diet The ketogenic diet is a high-fat, adequate-protein, low-carbohydrate diet that in medicine is used primarily to treat difficult-to-control (refractory) epilepsy in children. The diet forces the body to burn fats rather than carbohydrates. Normally, the carbohydrates contained in food are converted into glucose, which is then transported around the body and is particularly important in fueling brain function. However, if there is little carbohydrate in the diet, the liver converts fat into fatty acids and ketone bodies. The ketone bodies pass into the brain and replace glucose as an energy source.

It is sensitive to acetoacetate only, and the ratio of beta-hydroxybutyric to acetoacetate is shifted from a normal value of around 1:1 up to around 10:1 under severely ketoacetotic conditions, due to a changing redox milieu in the liver. Measuring acetoacetate alone will thus underestimate the accompanying beta-hydroxybutyrate if the standard conversion factor is applied.
